While emerging wengophone-2.0_rc2 the build process failed. The build called for -llzo, but with pacakge lzo-2.02-r1 the libraries are named /usr/lib/liblzo2.a. A simple symlink from /usr/lib/liblzo.a to /usr/lib/liblzo2.a caused the build to compile cleanly. So I suppose you could either fix the problem by adding that symlink to the lzo package or fixing the build for wengophone to use -llzo2 I apologize that I have no logs available. Please let me know if they (or other specifics) are necessary to resolving this.
